HARRY Yarns, or onicaeo, ILLINOIS I rusn-nornnn To all whom it mag concern Be it known that I, HARRY W. YOUNG, a

citizen of the United States, and a resident ,of the city of Chicago, county of Cook, and" State of Illinois, have invented certain new and useiul Improvements in Fuse-Holders,

of which the following is a specification.

My invention relates to improvements in fuse, holders and has for'its object the provision "of an improved holder for electrical blow-out fuses which is of simple construction'and'efiicient in use.

A further object of the invention is the provision of an electrical fuse holder which can only be used when fully assembled.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in -which, Figure 1 is a side elevation of a fuseholder embodying my invention, Fig. 2, a

longitudinal section of the same, Fig. 3, a view of an interior tube employed in the construction showing the end cap thereon insection, and Fig. 4, a detail view of an outer tube employed in the construction no showing the end cap thereonin section.

The preferred form. of construction as illustrated in the drawings comprises outer and innertubes 1 and 2 made of fiber o'r vf'other suitable insulating material and of asize to snugly telescope with each other as shown in Fig. 2. One end of outer tube 1 is closed by a metallic cap 3 which is se- -.;cured thereover as shown.

I The opposite end of tube 2 is closed by an end cap 4.- whichis of a size to fit snugly over the corresponding end of tube 1 as indicated in Fig.

v 2. End caps 3 and 4 serve to close the en of tubes 1 and 2 and also constitute the line terminals of the fuse as will be readily understood by those skilled in the art.

A- metallic clampingmember 5 issecured in each end of inner tube 2 and is provided with a coiiperatin clamping plate 6 and clamping, screw 7 or clamping the ends of fuse member 8 in position as indicated in lhe cap 4, terminal 5 andinner tube 2 may be riveted together in" the manner shown by inserting a suitable tool through opening 13 to hold the heads of the rivets as will be readily understood;

Specification of Letters itatent. Patented Apr. 28, 1914. Application filed January 1t), 1913. Serial No. 741,171. a I

End cap 3 is provided with .a contact screw 9 threaded therethrough and adapted to contact with the corresponding clamping member to effect electricalconnection between said end cap and said clamping member hen the tubes are assembled as indicated in Fig. 2. Tube {2 is provided'with a slot lO which is zigzag in shape at'its central portions but straight at its end portions 11 so as to permit the insertion of fuse member 8 therein, which is made zigza to fit said slot, said tubebeing also provlded with openings 12 Land 13 adapted to give access to the clamping screw I when tube 2 is Withdrawn from tube 1, end cap 4 being provided with an opening 14 registering with opening l3for this purpose.

In the construction'set forth, it will be noted, that the fuse member will be entirely inclcsed and protected and-that the parts may be readily separated or put together in replacing fuse members. By placing an end cap on each of the separable tubes it is rendered necessary to fully; assemble the holder before the same can be used and the separation and assembling of parts is greatly facilitated. It will also be noted that the fuse member employed must be properly shaped to pass through slot 10, so

that by giving slot 10 'difierent forms for fuses of diil'ere'nt capacities and making the corresponding fuse members to fit the corresponding slots only mistakes or tampering-- with the 'fuse are prevented.

While I have illustrated and describedv the preferred form of construction for carrying my invention into effect this is capable of variation and modification Without departing from the spirit of theinvention. Lthe'r'efore, do not wish to be limited to the precise details of construction set forth,

but'desire to avail myself of such variations and modifications as come within the scope of theappended claims.

- Having described my invention what I .clannasnew and desire to secure by Letters Patentis:

1. A device of the class described comprising two longitudinally separable telescopin tubes constituting a fuse casing, one of sai tubes being of a size to fit snugly within the other for substantially its entire length; a terminal contact member carried b Y each of said tubes but at opposite ends thereof: and a fuse member electrically connected with said contacts, substantially as described.

2. A device of the class described comprising two separable telescoping tubes constituting a fuse casing, one of said tubes being of a size to fit snugly within the other for substantially its entire length and provided with a slot therein adapted to permit insertionof a fusemember; a terminal contact member carried by each of said tubes; a fuse member of the same shape as and adapted to be inserted through said slot; clamping members in each end of the inner tube I adapted to clamp BlGCtIlCStl COIlDGCt-lOIlS between said clamping 'membersand said contacts, substantially as said fuse member; and

described. I p

.. 3. A device of the class'd'escribed comprising two separable telescoping tubes constitu'tinga fuse casing, one of said tubes be ng of a, size to fit snugly within the other for substantially its entire length and provided with a slot of distinctive shape adapted to permit the insertion of a fuse member; a terminal contact member carried by each of said tubes; a fuse member of the same shape as and adapted to beinserted through said slot; clamping members in each end of the inner tube adapted to clamp said fuse memher; and electrical connections between said clam ing members and said contacts, substantially as described.

' a 4. Adevice of the class described compris ing two separable telescoping insulating tubes constituting a fuse casing; a metallic cap secured over one end of the inner tube and of a'size to pass over the corresponding end of the outer tube; a metallic cap secured over the other end of the outer tube; and a fuse member electrically connected with said caps, substantially as described.

' of said inner tube, the clamping the corresponding end of said'tu e being electrically connected with the cap thereon; means for effecting an electrical connection member in between the cap on the outer tube and the other clamping member; and a fuse memberthe cap thereon, and there being open-- ings in the walls of said inner tube giving access to said clamping members; means for effecting .electrical connection between the cap on the outer tube and the other clamping member when said tubes are assembled; and a fuse member connected between said clamping members, substantially as described.

. 7. A device of the class described comprising a casing provided with a slot extending substantially the full. effective length of the tube and having a distinctive shape in its central portion but plain at its ends; clamping means in said casing adapted to clamp the ends of a fuse member; and a fuse member shaped to pass through said slot and engage said clamping means, substantially as described.

8. A device of the class described comprising a casing provided with a slot extending substantial y the full effective length of the tube and having a zig-zag shape in its central portion but plain at its ends; clamping means in said casing adapted to clamp the ends of a fusemember; and a fuse member shaped to pass through said slot and engage said clamping means, substantially as described. e

In testimony whereof I have signed my name to this specification in the presenceof two subscribing witnesses. HARRY W. YOUNG.
